Pulsar Oil Burning / Coolant Ingress (liquid-cooled models)

Generator emits white or bluish smoke from the exhaust, especially on startup.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn piston rings, Valve stem seal wear, Overfilled crankcase, Head gasket leak (liquid-cooled)

Safety first: Run the generator only in a well-ventilated outdoor location.

Check oil level: Ensure the oil is not overfilled; drain to the correct level if necessary.
Observe smoke behavior: Light smoke that clears after warm-up can be normal in cold weather. Continuous heavy smoke indicates internal wear.

Internal engine wear or head gasket issues require professional diagnosis and repair. Continued operation may worsen damage.
